Capacity is not power. Old batteries produce less power (volts times amps) no matter how full they are.

What threshold(s) are used by Apple to determine when to throttle?

If a new battery is purchased today, how many months of daily usage will cause Apple throttling to begin?

If a Samsung and Apple phone are purchased on the same day, used the same amount and benchmarked each day for 24 months, would their performance graphs look similar?

Regardless of what chemistry they are using, a lithium cell should be capable of producing more than enough power for a cellphone at any residual capacity before it becomes useless. You aren't discharging at more than 0.5C on a portable device.
